Evolution Exam

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual
• population
• species
• fossil

Which of the following is a fossil?

• a plant that has recently died
• a group of organisms that can reproduce
• a structure or organ that no longer functions
• a trace of an organisms that existed in the past

Over time, adaptions can lead populations to experience 

• environmental changes
• genetic changes
• geological changes
• extinction

what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands
• all species on one of the islands
• identical species on all the islands
• the same species as North America

which of the folllowing is an exammple of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the wings of an ostrich

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• gene flow
• gene pool
• allele

The five-factors gene flow, genetic drift, mutation, natural selection and ....

• non-random mating
• controlled mating
• emigration
• immigration

Mutations are important because they bring about -

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

• combining of tow species to form one with different traits
• isolation that affects mating behaviors
• timing of mating that prevents normal sexual selection
